Fish Casserole
Description
The Fish Casserole begins with peeled and boiled potato chunks mashed with a small amount of dairy-free butter and plant-based milk to create a smooth topping. Meanwhile, a sauce is prepared by cooking green onions in butter, then adding cornstarch and gradually whisking in more milk to form a thickened base. Dijon mustard, ground nutmeg, and finely chopped anchovy fillets are stirred in to provide depth of flavor. The fish pie mix, baby spinach, and peas are added to this sauce, which is then transferred to a baking dish and layered with the mashed potatoes on top. Baking in a preheated oven at 400°F for 25 minutes forms a golden, bubbling casserole.
The dish combines tender fish chunks with a creamy, slightly tangy sauce and soft vegetables, balanced by the fluffy mashed potato crust. The inclusion of anchovies enhances umami without a strong fishy taste, and nutmeg adds warmth. This casserole is filling and can serve as a substantial main course.
For best results, use similarly sized fish chunks to ensure even cooking, and fresh ingredients for flavor and texture. The casserole should be served hot and rested briefly after baking to allow flavors to meld. Adjust seasoning as preferred, and cover with foil if browned too quickly during baking.
Each serving has 7 WW Blue Plan SmartPoints, making it suitable for those tracking points. The recipe is versatile, allowing additional vegetables to be added if desired.
